If you are having trouble accessing Zoom, contact the event staff using the xtUML Community Google Hangout.

In the Agenda of Presentations, each presentation is linked to a YouTube video (most links are live only on conference day). If for some reason the Zoom rendering of the presentation is faulty, you can watch the presentation on YouTube. However, pay attention and rejoin the live conference for Q&A! You can come back to these videos after the conference is over.

Participant Instructional Emails

Participants were sent emails ahead of the conference. Those emails are repeated here for convenience ordered from most to least recent.

Participant Instructions (3)

Our presenters this year are the best!  As presentations are in progress, type questions in the Zoom chat.  You may use 1-on-1 channels to chat with other participants.

The conference has several interactive elements.  You will join Zoom breakout rooms throughout the day to hear people introducing themselves and answering the "question of the day".  We also have debates scheduled in the afternoon with the expectation of arriving at consensus on three constructive topics. Join enthusiastically; these always end up being the best part of a Zoom conference.

For each of these breakout sessions, you will choose room 1, 2 or 3 from your Zoom control panel.

To make these interactive sessions as pleasant as possible, pay attention to the sound quality from your machine.  First, be in a quiet place.  A PC microphone is probably fine, but head sets, podcast mics or AirPods are better. Have light on your face, minimal light behind you and your camera at eye level.

You will be asked to introduce yourself, your organization and your connection to the Shlaer-Mellor xtUML Community.  Think about this ahead of time and be colorful!

Plan for your favorite drink at virtual happy hour after the conference proper. Be prepared to share about what you are drinking.

Participant Instructions (2)

COVID-19 played one final trick and caused cancellation of the physical gathering in Portsmouth.  England is in full lockdown beginning on conference day.  (!!)  The conference is now 100% remote/virtual.  We were prepared for this and will press on!

Very importantly, the conference web site is your primary source of information.  Even on conference day it will get updated to help deal with whatever might happen.

The agenda has been re-sequenced to make it easier for presenters in widely spread out time zones (+/- 8 hours!).  View the agenda on the web site.

This conference will be a Zoom marathon.  Prepare to have a comfortable, quiet, soft-surface room.  Plan for your food and drink.  Have good internet, preferably wired.  Flaky WiFi makes for a miserable day.  If your internet at home is lousy, find an alternate location.

Participant Instructions (1)

Hello from the UK and Zoom-land…​

If you have never used Zoom, please install and practice on Zoom before the conference! (Install the application rather than rely on the web browser version.)

Most of the presenters are presenting from remote places.

All but a few of the presentations are pre-recorded, will be played and then followed with live Question and Answer. Plan to type your questions into the Zoom chat even while the presentation is playing. Presenters may actually answer some question in real time! If not, we will have assistants watching this feed to help choose the best questions and call on you at the end.

Be thinking about comfort, quiet, fast internet, microphone purchase, time zones, meals, questions for panel members, enthusiastic debate of xtUML topics, a special drink for happy hour, …​

Last Minute Instructions for Presenters

  • Please be present and attentive during your presentation.

  • Monitor the Zoom chat stream and attempt to answer questions in real time.

  • Upon completion of the presentation, you will go live to answer audience questions.

What is this?

xtUML Days 2020 UK is a modeling conference and represents the 7th edition of xtUML Days. (See Previous xtUML Days.) xtUML Days is the most dense gathering of the year of Shlaer-Mellor modelers. The xtUML Community meets to collaborate on Modeling, Method and Tooling.

The central topic of the conference is end-to-end modeling, execution, translation and deployment of models-as-code in mission critical settings employing rigorous methodology. The unifying theme is practical, actual, industrial application modeling within production installations. Attendees will network with engineers, scientists and educators who understand executable and translatable modeling as applied in active systems.

In 2020, a special focus will be continued to extend and clarify the Shlaer-Mellor Method in light of undocumented developments over the last several years.

Also in focus:

  • Method advances (specifically convergence of PT and K-C dialects)

  • Tooling Refinements

  • Incremental Adoption

  • Model Compilation

The xtUML Community is keen to exchange expertise and learn from one another. xtUML Days provides a forum for developers to share best practices and influence the direction of the technology. xtUML Days hereby solicits compelling papers and presentations that exhibit method advances, tooling improvements and application experience in Shlaer-Mellor modeling and related Executable/Translatable modeling. This year attendees represent One Fact, UK Crown, BAE Systems, ROGO, Northrop Grumman, Aurora Consulting, Software Improvements, L3, Thales, Toyo Corporation, ICS, FrogOOA, Kyushu University, University of Southampton and Jönköping University.

Keynote Speaker

Stephen Mellor

We are pleased to announce that the xtUML Days 2020 Portsmouth keynote speaker is Stephen J. Mellor, co-author of the Shlaer–Mellor Method and Executable UML, and signatory to the Agile Manifesto. Mellor has been working with methods, particularly executable methods, for real-time and embedded systems for four decades.

He explains, with clarity and humor, the intricacies of real-time and embedded systems model-driven development, in both presentations and text. He is the author of several books:

Stephen presently serves as Chief Technology Officer of the industrial internet CONSORTIUM (IIC).

Other Presenters

In addition to Stephen Mellor other key Shlaer-Mellor community members plan to participate including Colin Carter, Ian Wilkie, Leon Starr, Marc Balcer and others.

Portsmouth

Venue

xtUML Days 2020 will be hosted virtually on Zoom. This platform is familiar to most and supports interaction with people as well as access to presentations.

Registration
